Manual drive for a connector with earthing, line-side mounting, rotary motion of NRA E-18 w.I 03-522

Manual drive for overhead disconnectors – reliability and ease of use

This manual drive, designed for grounded disconnectors, is a key element in medium voltage disconnecting systems. It enables safe and controlled operation of the disconnector, both during maintenance work and in emergency situations. Line-side mounting provides convenient access and minimizes the risk of disruption to power supply. The rotational movement of the NRA-u E-18 w.I drive guarantees smooth and precise operation of the disconnector mechanism.

Design and application

The NRA(u) type manual drive is an integral part of ALPAR overhead disconnectors, providing manual control of the circuit connection and disconnection process. It is mounted using two M10 screws to the disconnector drive mechanism, ensuring a stable and secure connection. The drive design is designed for ease of operator use, and its solid construction guarantees long-term reliability even in harsh weather conditions. This drive is used in medium voltage (24 kV) overhead lines where manual control of disconnectors is required.
